Title: Device for enabling the occupants of a motor vehicle to practice the correct action when the motor vehicle plunges into water
Inventor: LANDMANN REINHARD
IPC: G09B9/04
Filed: 1993-06-07
Abstract: The device simulates accident sequences which occur if a motor vehicle leaves a dry carriageway and plunges into water where it can rotate about its longitudinal and its transverse axes.

Patent DE-4402213-A1 (DE)
Title: Viscous coupling for vehicle
Inventor: ANDERSON FLETCHER MICHAEL
IPC: F16D35/00
Filed: 1994-01-26
Abstract: The viscous coupling has a hub and housing with a disc space between them. One set of discs is attached to the housing and one set is rotationally attached to the hub. The second set of discs can move axially and is provided with radial slots (42) bounded by lipped profiles. The lip thickness is largest near the hub and tapers towards the edge of the discs.  The lip profiles ensure that the discs first make contact near the hub and with increasing pressure difference between the hub and the shaft the discs are pressed further together with a progressive contact along the tapering lipped areas. The discs rotate freely at small differences in the speeds of the shaft and the housing and are progressively pressed together as the relative speeds increase.

Title: Digitally controlled communication terminal appts. circuitry
Inventor: KLING MANFRED
IPC: H04L29/08
Filed: 1994-06-28
Abstract: Timing lines and data lines are connected between an interface associated with the connection lines and an internal interface. In the internal interface, a conversion from digital data to analog values and vice versa takes place. A control unit, connected to the data and timing lines, receives and generates signalling data. The data line transmitting and reception channel (EK) is directly connected to the serial input (E) of the control unit (SE). The data line serving a transmission channel (SK) is connected via a resistor (W) to the serial output (A) of the control unit (SE). A clock counter (TZ) is brought into a predetermined output position from a frame clock (RT) and is controlled by a bit rate (BT). It carries out a number of steps corresponding to the distance of the signalling bits from the frame clock (RT). A D bit clock is generated which is fed to the control unit (SE). The latter contains programs to carry out the functions of a standard protocol for inserting and removing signal bits (D) from the reception channel (EK) or into the transmission channel (SK). The bit inserted into the transmission channel (SK) is provided at the serial output (A) of the controller (SE) at an edge of the D bit clock (DT). It is only effective via the resistor (W) when no useful data bits (B1,B2) are sent on the data line of the transmission channel. The signal bit removed from the reception channel (EK) is fed with a clock edge of the D bit clock (DT) to the controller (SE).
